chmod -R 0600 /opt/hosts/host.to.check/

#SSH接続確認
ssh -v serverspec@host-to-check.com -i /opt/hosts/host.to.check/ssh.key

■SSH接続設定

vim ~/.ssh/config

----

■接続先サーバーでチェック用ユーザーがsudo出来るように準備 【重要】visudoの設定は必ず最後に戻しておくこと！！

useradd serverspec
# visudo

su - serverspec
mkdir ~/.ssh
vi ~/.ssh/autorized_keys
# 公開鍵追加

chmod 0700 ~/.ssh
chmod 0600 ~/.ssh/autorized_keys
